How to Retrieve Plain Text Responses from HTTP GET Requests in Golang

A frequently encountered task when working with HTTP requests is handling plain text responses. In Golang, retrieving this text requires specific steps. Consider the following scenario:

url := "http://someurl.com"<br>response, err := http.Get(url)<br>if err != nil {</p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">log.Fatal(err)

Copy after login

}
defer response.Body.Close()

// How to grab the plain text response?

To access the plain text response, follow these steps:

1. Read the Response Body

Utilize the ioutil.ReadAll function to read the entire response body into a byte array:

responseData, err := ioutil.ReadAll(response.Body)
if err != nil {
    log.Fatal(err)
}

2. Convert Response Bytes to String

Since the response is plain text, convert the byte array to a string:

responseString := string(responseData)

3. Check the Result

Display the retrieved plain text response string for confirmation:

fmt.Println(responseString)

Sample Code:

package main

import (
    "fmt"
    "io/ioutil"
    "log"
    "net/http"
)

func main() {
    url := "http://country.io/capital.json"
    response, err := http.Get(url)
    if err != nil {
        log.Fatal(err)
    }
    defer response.Body.Close()

    responseData, err := ioutil.ReadAll(response.Body)
    if err != nil {
        log.Fatal(err)
    }

    responseString := string(responseData)

    fmt.Println(responseString)
}
